(1) Indoor air quality work
The 112-year plan has carried out direct-reading instrument inspections for a total of 27 listed units and 17 non-listed units in the county. The inspections began in April, and the CO2 test results of the listed units were between 400 and 400. Between 700ppm and non-managed sites, CO2 is also below 700ppm. All sites comply with regulatory standards. In May, 5 managed or non-managed places with poor indoor air or special conditions were selected from the inspection units, and 3 experts and scholars related to indoor management were invited to provide on-site diagnosis services by providing improvement measures. It is also planned to track the achievement of autonomous labels for listed and non-managed places in the county. From January to December, 7 companies have completed independent management labels (excellent grade). 6 companies received the mark and 1 company received the good mark). As for non-listed places, we actively promoted the self-management label during inspections of 17 non-listed places and encouraged them to actively apply. We also successfully guided the non-listed unit Geyike Baby Care Center to apply for the excellent grade mark.
(2) Operation and maintenance of air quality monitoring stations
Maintain the normal operation of the air quality manual measuring stations (3 stations) and automatic measuring stations (2 stations) within the county's jurisdiction to complete the collection and placement of TSP, PM10, PM2.5, and falling dust at the three manual measuring stations twice a month. Maintenance work; the automatic measuring station part also completes the regular maintenance of the two stations twice a month.
1. Manual measuring station operation and maintenance operations and monitoring results
The TSP, PM10, and PM2.5 samplers in the three manual measurement stations were under normal operation and regular maintenance work. As of the end of December 2012, a total of 24 regular maintenance work had been performed, and no temporary failures occurred that required additional maintenance. situation and perform multi-point calibration and maintenance on a quarterly basis. The average measured value of TSP from January to December at the 112-year manual measuring station was 29 μg/m3, an increase of 82% from the average of the same period last year and an increase of 25% from the average of the same period in the previous three years. The average measured value of PM10 from January to December was 20 μg/m3, an average increase of 27% from the same period last year, and the same as the average value of the same period in the previous three years. The average measured value of PM2.5 from January to December was 8 μg/m3, an increase of 33% from the average value of the same period last year and the same as the same period of the previous three years. (The plan inspection found that there were construction projects near the measuring station. The rainfall from January to May in 2011 was 606mm, and the rainfall from January to May 2012 was 414mm. The rainfall from October to November 2011 was 943mm, while the rainfall from October to November 2012 was 943mm. 321mm, the reason for the increase in mass concentration may be related to construction projects and rainfall). The dust volume in 2011 was not much different from that in the same period in 2011. The average dust volume from January to December in 2012 was 2.7 (metric tons/square kilometer/month), which complies with regulatory standards.
(PM10-year standard value is 50μg/m3, PM2.5-year standard value is 15μg/m3)
2. Automatic measuring station operation and maintenance operations and monitoring results
This year's plan requires regular maintenance twice a month. As of the end of December 2020, our team has conducted a total of 24 regular maintenance works on the monitoring equipment of Fenglin Station, and performs annual maintenance and calibration of the automatic station on a quarterly basis. During the implementation of this project, the data availability rate of Fenglin Station from January to December averaged over 85%, and the monthly sampling data of the automatic station were submitted as scheduled. The figure shows that the monitoring items such as SO2, NO2, CO, and O3 at Fenglin Station from January to December 2012 are not much different from those at the Hualien Station of the Ministry of Environment. In addition, the average measured value of PM10 at Fenglin Station from January to December 112 was 18 μg/m3, an increase of 5.3% from the average of the same period last year, and a decrease of 24% from the average of the same period in the previous three years. The average PM10 in Yuli from January to December was 16 μg/m3, an increase of 23% from the average of the same period last year, and an increase of 14% from the average of the same period in the previous three years.(PM10-year standard value 50μg/m3)
3. Local characteristics of control effectiveness and results PM10 and PM2.5 related control or research work
1. The average mass concentrations of PM10, PM2.5 and PM2.5-10 measured at designated measuring stations in 2023 without distinguishing the influence of air flow sources are 19.2, 7.7 and 11.5μg/m3 respectively; under the influence of the northeast monsoon, they are 21.4 respectively. , 8.1 and 13.3 μg/m3; under the influence of high-pressure return flow, they are 20.2, 8.9 and 11.3 μg/m3 respectively; under the influence of Pacific high pressure, they are 17.2, 6.8 and 10.4 μg/m3 respectively; under the influence of southwest airflow, they are 16.9, 6.7 and 10.2 μg respectively. /m3; the PM2.5 collected under the influence of mainland China are 23.2, 8.4 and 14.8 μg/m3 respectively. The PM2.5 collected under the influence of high-pressure return flow is higher than other air flow patterns, and its mass concentration is 8.9 μg/m3, which is lower than the annual average air quality. The standard is 15 μg/m3 (59% of the annual average standard), which shows that Hualien’s air quality in 2023 will not be significantly affected by air pollutants imported from abroad.
2. The dominant species components of water-soluble ions in PM2.5 particles collected at designated measuring stations in Hualien County in 2023 under the influence of different air flow sources are all dominated by SO42- (accounting for 20~26%), while PM2.5-10 is in the Northeast The dominant species under the influence of monsoon type is NO3- (accounting for 11%), the dominant species under the influence of high pressure return, Pacific high pressure and southwest airflow is OC (accounting for 13~25%), and the dominant species originating from mainland China is NO3- (accounting for 11%) %), the source of water-soluble ions of PM2.5 particles is estimated to be highest in secondary derived salts, accounting for 34~39%, while PM2.5-10 particles are seawater-related ions (accounting for 13~26%) and Secondary derived salts (8~12%) account for the top two places. The estimated results of using the chloride ion loss method to estimate the composition of water-soluble ions in particles show that all PM2.5 particles contain ammonium sulfate salts (accounting for 24~31%) as the main species; PM2.5-10 particles contain sodium chloride (accounting for 24~31%). 7~20%) and sodium nitrate (8~15%) are the dominant species.
3. The overall PM2.5 mass concentration in 2023 is higher than the same period in 2022, and slightly higher than the concentration in the same period in 2021 (7.6 μg/m3). The airflow closely related to overseas migration originates from PM2 collected under the influence of mainland China. The average concentration of 5 particles in the past three years is divided into 8.4 μg/m3 in 2021; 9.3 μg/m3 in 2022 and 8.4 μg/m3 in 2023. Due to the reduction of imported pollution from abroad, the control of regional pollution sources is more important.
4. Recommendations for regional PM2.5 pollution source control strategies are as follows: (1) Continue to strengthen the control of traffic pollution sources: including guiding the elimination of old diesel vehicles and motorcycles, promoting low-pollution transportation (electric vehicles or hybrid vehicles), etc. (2) Strengthen the guidance on catering oil fume control, especially to control the effectiveness of pollution prevention and control facilities. More active measures should be taken. (3) Through environmental education, we should take root in the behavior of burning incense and burning gold in folk activities, so that religious and folk groups can spontaneously reduce incense and money from the inside out. (4) Strengthen road cleaning work to avoid repeated rise of street dust, causing an increase in PM2.5 concentration in heavy traffic areas. (5) Continue to cooperate with the academic community to conduct research and analysis on the characteristics and control actions of regionally derived particles as a basis for the evaluation of control effectiveness.(PM10-year standard value is 35μg/m3, PM2.5-year standard value is 15μg/m3)
(3) Detection of harmful air pollutants
In accordance with the assessment of the Ministry of Environment or other relevant regulations, the concentration survey of harmful air pollutants in the atmospheric environment in this county requires a total of 4 quarters of monitoring operations. The first to fourth quarter testing operations have been completed from January to December (located at the Zhongzheng Elementary School monitoring station of the Ministry of Environment), and the results are all in compliance with regulatory standards.
(4) Greening and air quality purification areas
In order to continue the pollution purification work, this year, the project assists the Hualien County Environmental Protection Bureau in continuing to promote air quality purification area inspections and guidance, discovers deficiencies and urges management units to improve, and holds a briefing session on the application of air quality purification areas to assist with updates. Many towns, towns and cities have applied to set up air purification areas with the goal of maintaining good air quality in the county. From January to December, a total of 144 inspections of existing air purification areas in the county were completed, 24 new inspection operations were established (no new bases were established in 111 years, so inspections of exposed areas will be changed), and 4 on-site assessments of air purification areas were completed , completed the adoption of 24 bases, completed subsidies for 8 idle vacant lands of more than 4 hectares, and completed carbon sink surveys for 13 bases, with a total carbon reduction of 241.209 metric tons/CO2. 112 has conducted its own air quality purification area evaluation operations, and has completed Units with excellent performance will be submitted to the Ministry of Environment to participate in the "112th Air Quality Purification Zone Selection Activity". The activity has not yet been processed.
(5) Take a big breath
The results of the average PM2.5 mass concentration measurement at low-carbon attractions in Hualien County from March to October 2012 in conjunction with the county government's "Breathe Big Breath" show that the average PM2.5 mass concentration measured by real-time PM2.5 measuring instruments at various low-carbon attractions in Hualien County The mass concentration varied between 4.7 and 14.6 μg/m3, with an average value of 7.7 μg/m3, with the highest value measured in the Dongdamen Night Market commercial district. During the same period, the mass concentration of PM2.5 measured at the Hualien Air Products Station was between 5.9 It varies between ~ 10.8 μg/m3, with an average value of 8.0 μg/m3. The PM2.5 mass concentrations measured at low-carbon attractions are higher than those in Hualien except for Dongdamen Night Market Commercial District and Guangfu Sugar Factory. Except for the measured value of Kongpin Station, all other scenic spots are lower than the measured value of Kongpin Station.
There are three low-carbon scenic spots with higher PM2.5 measured values than those measured at the Kongpin Station, namely: Dongdaemun Night Market Commercial District, Ji'an Keishuyuan and Guangfu Sugar Factory. The measured PM2.5 values of other scenic spots are all lower. The value is measured at the empty product station. The Dongdaemun Night Market business district is mainly affected by catering fumes, Ji'an Keishuyuan is mainly affected by incense burning activities, and Guangfu Sugar Factory is mainly affected by artificial smoking, making its measured value higher than that of the empty product station. Among them, Dongdaemun Night Market, which has the highest PM2.5 measurement value, was affected by the fumes from restaurants, causing the peak PM2.5 measurement value to increase to 48 μg/m3, but the average value is still at the "good" level.(PM2.5 annual standard value 15μg/m3)
(6) Continuous flue monitoring system CEMS
It is planned to carry out CGA, RATA, OP, potential and signal comparison, on-site inspection and other inspections of the five major factories in the county (Taiwan Cement Heping Plant, Asia Cement Hualien Plant, Heping Power Plant, Chung Hwa Pulp Mill, and TCC Hualien shutdown status) in accordance with the contract specifications. Operations and results are in compliance with regulatory limits.
From January to December in 2012, it is planned to complete 13 CGA standard gas inspection operations (including 2 Chinese paper inspections); 44 RATA supervision and inspection operations; 68 supervision and regular inspection OP operations; and 36 potential and signal input operations. Comparison operation (continuation of 108 years of innovative practice instrument comparison); the effective monitoring time percentage is 97%. According to statistics, all operations from January to December were in compliance with regulatory standards.
RATA and CGA test and verification results evaluate the current instrument operation and maintenance status of each plant. The relative accuracy of RATA and the accuracy of CGA verification for each monitoring item of Heping Power Plant P001 and P002 are in compliance with regulations. There is no long-term negative deviation in the CGA test results. , in the past three years, on-site inspections and inspections have been carried out to check the operation and maintenance status in accordance with the maintenance items and frequency in the confirmation report, and the instrument is in good condition.
(Standard gas check accuracy%: -15%≦(CGA) accuracy≦15%)
(Relative accuracy RA≦10%)

(8) Innovation as "Public-private collaboration between indoor empty products and big breaths makes it more attractive"
In order to promote and expand the benefits of indoor air quality, we focus on indoor air quality management in non-listed places. This project plans to engage companies to jointly promote indoor air quality. In addition to demonstrating support for the government's determination to achieve net-zero carbon emissions in 2030, it can also fulfill corporate responsibilities and make more efforts to promote friendly indoor air quality. This positive corporate image can encourage more Many enterprises actively participated, thus forming a model of cooperation between private enterprises and the government to create a win-win situation. The execution results of the plan from January to December are as follows:
1. In order to create an indoor air quality demonstration site, publicize the quality of the air in the place where people live, encourage other companies to pay attention to indoor air quality and improve corporate CSR, and also ensure the health and safety of the people, the environmental protection park set up can better empower Environmental education significance. It can increase the willingness of the county's second batch of 14 listed places and 19 categories of non-listed places to apply for self-management labels.
2. Testing data (CO2, PM10, HCHO) will be tested in the first and second half of each month, and will be published in the Environmental Protection World.
3. We have partnered with one company (TOYOTA Motors) to jointly build a good indoor air quality demonstration site, conduct indoor CO2 indoor air pollutant testing announced by the Ministry of Environment, and announce the testing data at the entrance of the site. In addition, an environmental protection area is set up in the venue (vehicle display room or car owner rest area), mainly to show corporate support and assistance to the government in promoting the determination and policy of net-zero carbon emissions in 2030. The county Environmental Protection Bureau provides CO2 display boards for participating companies (through a professional team Use after calibration), allowing the public to enter the corporate display space or exhibition area, and the air quality data can be displayed in real time. It not only controls indoor air quality with energy efficiency, but also enables companies to independently undertake environmental education and contribute more efforts.
4. In September, an indoor air product environmental protection lecture will be held. An environmental lecture and environmental fun competition will be held at the TOYOTA Eastern Auto Showroom. Listed or uncontrolled places announced by the Ministry of Environment in the county and the general public will be invited to participate in the event. This positive corporate image can encourage more companies to actively participate, thereby forming a model for private companies and the government to work together to create a win-win situation.
5. The determination to integrate public institutions and enterprises should be widely publicized through online media and other means for the purpose of public-private collaboration to jointly safeguard the health of the people.
6. Complete the guidance for non-listed places - child care centers to apply for the excellent label.
